There is a ton of information on Cayman mpg - see the threads below. A search will likely yield a lot more.

AS to my experience, after the rings fully seat (approx 8,000 miles) and with mixed driving, I get about 16MPG. I do not commute or drive in heavy traffic usually, though I do drive in city scenes, lights, stop signs, higways, freeways, etc.
